Info sui prodotti "Microstirrer"

When Vernier introduced the new Drop Counter, they decided to include a Vernier Microstirrer to enhance stirring. Since then, they've had many requests to have this as a separate product.

The Microstirrer takes the place of the stirring bar that is typically used with a laboratory magnetic stirrer. The new Vernier Microstirrer easily attaches to the end of a pH Sensor, Conductivity Probe, Dissolved Oxygen Probe or Ion-Selective Electrode. When the magnetic stirrer plate (required, but not included) is turned on, its magnetic field turns the paddle wheel of the Microstirrer, resulting in enhanced stirring near the electrode tip. The Microstirrer works with any magnetic stirrer.

Stir Station

La Stir Station è un agitatore magnetico combinato con un supporto ad anello. La stazione di mescolamento gestisce in modo efficiente becher e altri contenitori da 50 mL e da un litro (800 mL di capacità pratica). Funziona in modo efficiente con becher con un'ampia gamma di dimensioni e forme di barre di mescolamento magnetico. Utilizza un controllo della velocità ad anello chiuso, facilitando così la regolazione della velocità di agitazione (50-1250 RPM).La piattaforma di agitazione è illuminata da tre LED bianchi freddi. I LED sono posizionati sotto la piattaforma di agitazione per fornire un'ottima illuminazione di un contenitore di vetro di liquido.Include un supporto ad anello da 18 pollici rimovibile comodamente posizionato e fissato alla base dell'agitatore, ad una distanza tale da ospitare facilmente la maggior parte dei morsetti di servizio.Funziona con alimentazione AC (adattatore incluso) o con quattro batterie C (non incluse).È sufficientemente robusto per azionare la maggior parte delle barre di agitazione magnetiche di dimensioni comuni o un Microstirrer Vernier.Ha una piastra di mescolamento in plastica resistente alle sostanze chimiche. Inclusi: Stazione di Vernier Stir Microagitatore Vernier Barra di agitazione (4 cm) Adattatore di alimentazione DC da 6 volt Supporto ad anello (46 cm) Manuale dell' utente

Go Direct™ Conductivity Probe

The Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform conductivity studies as a function of temperature. The Go Direct Conductivity Probe has a range of 0 to 20,000 μS/cm to provide optimal precision in any given range. An alternating current at its electrodes prevents polarization and electrolysis, reducing contamination of solutions. Its ABS-body graphite electrode resists the corrosion typical in metal electrodes. The Go Direct Conductivity Probe can be used in a variety of experiments: Demonstrate diffusion of ions through membranes. Investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Measure Total Dissolved Solids (TDS). Specifications: Range: 0 to 20,000 μS/cm (0 to 10,000 mg/L TDS) Temperature compensation: Automatic from 5 to 35°C, can be turned off Temperature range (can be placed in): 0 to 80°C Cell constant: 1.0 cm-1 Description: ABS body, parallel carbon (graphite) electrodes Dimensions: 12 mm OD and 120 mm length Connections: Wireless: Bluetooth Wired: USB Included Go Direct Conductivity Probe Micro USB Cable

Conductivity Probe

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.

Tris-Compatible Flat pH Sensor

Use the Tris-Compatible Flat pH Sensor to measure the pH of a solution or semisolid, such as food or soil. The Tris-Compatible Flat pH Sensor is a highly versatile sensor. Because the glass membrane is flat instead of a bulb, it is more durable, easier to clean, and allows for flat surface measurements or smaller sample sizes. It features a sealed, gel-filled, double-junction electrode, making it compatible with Tris buffers and solutions containing proteins or sulfides. The flat glass shape also makes it useful for measuring the pH of semisolids such as food or soil slurries. Range:pH 0–14 User manual

Drop Counter

Use the Drop Counter to perform accurate, automatic titrations. Record the number of drops or calibrate the drop size to record volume of titrant added during a titration. The Drop Counter precisely records the number of drops of titrant added during a titration, which is automatically converted into volume. It may be used in conjunction with other sensors, such as a pH Sensor (PH-BTA), Conductivity Probe (CON-BTA), or ORP Sensor (ORP-BTD) to perform conductimetric or potentiometric titrations. Adjustable clamp, fits most laboratory ring stands and lattices Wide drop-detecting area Large sensor slot, fits most conventional stick-style sensors Smaller, adjustable slot for temperature sensors Accurate drop counting at rates up to 6 drops/second User manual

Electrode Support

The Vernier Electrode Support connects to all standard ring-stand posts to keep sensors firmly in place during an experiment. The Electrode Support is a great complement to the Vernier Stir Station, as well as a perfect holder for many sensors. It is built to connect to all standard ring-stand posts; its large-handled locking nut keeps your sensors firmly in place. The larger opening (13 mm in diameter) is perfect for our pH, ISE, Conductivity and ORP sensors. The smaller opening (5 mm) is designed to hold our Stainless Steel Temperature Probe or the Vernier Go!Temp. The clamp end makes connecting to ring stands easy, accommodating post diameters between ~0.5 and 1 cm. The grooves on the Electrode Support to hold the wire leads for electroplating or electrolysis experiments.
